While many plants have some amino acids, they don’t have enough of the right combinations to be biologically useful (liebig’s barrel). It’s dangerous to assume all plants are protein, because that is a measure of crude protein (nitrogen estimate) and not actually amino acid ratios. Make sure whatever plant your eating actually has a biologically meaningful diaas score.
I try to teach people about protein and bioavailability all the time!
